In a video projector, first and second light sources respectively emit first and second collimated, white light beam, a luminance optical modulation means modulates the first light beam in accordance with a luminance signal of an input video signal, a chrominance optical modulation means modulates the second light beam in accordance with a chrominance signal of the input video signal, a first projecting means projects the first light beam having been modulated by the luminance optical modulation means onto a projection screen to form a projected luminance image on the screen, and a second projecting means projects the second light beam having been modulated by the chrominance optical modulation means onto the projection screen to form a projected chrominance image on the screen. The projected luminance image and the projected chrominance image are superimposed with each other on the screen to form a full color image.
